The territory of our ancestors should be defended to the death; we should not compromise it with others. The text "Five Warriors of Langya Mountain" mainly talks about the five warriors who were not afraid of death in order to fight against the Japanese army. Li Gang, a famous official in the Song Dynasty, said that "the ancestral territory should be defended to the death and cannot be compared with others." The Five Heroes of Langya Mountain are five heroes of the Eighth Route Army who bravely fought against the Japanese and the puppet Manchukuo troops in the Langya Mountain battle in Yi County, Baoding City, Hebei Province during the Anti-Japanese War. They were Ma Baoyu, Ge Zhenlin, Song Xueyi, Hu Delin, and Hu Fucai.
